Sepp Blatter has said he will remain as Fifa president despite criminal proceedings being opened against him by Swiss investigators. An investigation was opened into Blatter on Friday over suspicions of criminal mismanagement.

The Swiss is suspected of signing a contract that was “unfavourable to Fifa” and making a “disloyal payment” to Uefa president Michel Platini. Blatter, 79, said he “had done nothing illegal or improper”.
